Anger

so I (F24) will be having a great day and someone will say something not mean or anything towards me and it’s like a switch flicks and I’m instantly angry. Like throwing stuff. Breaking things. Yelling. And I don’t know why I do this. I’ve lost friends because of it. Ruined relationships with people. I don’t know how to fix it. My grandma says it’s like talking to Dr. Jekyll and Mr. Hyde how do I go about this? Do I talk to a doctor?
